Advancements in digital twin. Distributed energy resources simulation for supporting system level scenario evaluation

This paper introduces a framework for grid analysis and simulation by the integration of an open-source simulator into a Digital Twin (DT) environment, where the simulator is built in C++ for high-performance applications. It provides real-time and offline simulation capabilities, making it adaptable to various grid management needs such as comprehensive system-level modelling, predictive maintenance, and real-time grid monitoring. A case study with ASM Terni demonstrates the effectiveness in the coordination of Distributed Energy Resources (DERs). The framework is built upon a modular architecture inspired by the open-source project SOGNO, enhancing the scalability and flexibility. In addition, unit testing and code scanning mechanisms ensure the reliability of the solution for sustainable energy management in modern distribution systems.
